I' Application filed June 24,1887. Seal No. 242,401.. (No model.)

` To all whom it may concern.- Beit known that `JAMES. J. KIRBY, acitizen of the United States, formerlyresiding at Moline, county of RockIsland, State of Illinois, deceased, has inventeda newand useful Machinefor Forming 'Wheel-Rims, of which the following is a specification.

The object of this invention is to construct a machine for forming therims of car-wheels Io by rollerpressure.

The peculiarities, utility,aud novelty ofthe 'invention are belowdescribed and claimed.

In general terms the main essentials of-the machine consist in a set ofthree rollers for `I54 formingan internal dangeon one edge of the`wheel-rim and a setof two rollers for forming the external ange ofthetread part of the Wheel, and duringthe operation these sets of rollersact separately and conjointly in per- 2o formingdift'erentfunctions,asbelowexplained.

In the drawings forming a part of this specification,Figure 1 isa sideelevation with parts broken and the wheel -rim`in section; Fig. 2, aplan' with parts broken away; Fig. 3, broken 25 lettered details of Fig.1, enlarged; Fig. 4, a

plan of parts in Fig. 3, with the roller-axles in cross'section belowthe rollers, the latter be- "ing shown in dotted lines; Fig'.4 5, abroken piece of the wheel-rim prior to its subjection 3o to the machine;and Fig. 6 is the' same after treatment, these two last figures being inperspective. l

Referring to the lettered parts of the drawings, A. is the top ofthemachineframe,and A 3 5 is the` bottom thereof. At y y' are two shaftsgear-connected, having bearings in the frame,

and are provided at the upper en'ds wit-h rollers ct'ct. The roller aconforms in shape to the exterior of the wheel-rim B when completed,

4o4 and the `roller a conforms in shape to the interior of said rim. Tothis end the rollerais .flanged at the top and tapered at the-base.'

The roller a' is dared outat the base to conform tothetaper of the otherroller, a. These portions ofthe roll rs a a form the external flange Iof tlic 'wheel-rim. Their form in Figs. l and 2 is such that the flangeis formed scalloped; but as this is a matter of vchoice the termstapered and flared 7 as used above are deemed sufficiently specific. Itwill be ob- 5o served that the roller a is shorter than that portion ofthe roller a below its flange. Thus in'use the flange z projectsoverjthe end of the roller a', leaving a space between said end of theroller and the iiange corresponding to the v,thickness of the metal fromwhich the vrim is made. v At u u are two like shafts', alsogear-connected,asinFig.l. Theseshafts are provided at the top withrollers c c. The periphery of these 6o rollers is straight vertically,or nearly so, except that they are out away at the base to accommodatethe' external ila-nge of thevwheela'im.

The internal iiange, It, (see Fig. 6,) of the -wheel-'rim is formed bycrimping the edge 65 over theu-pper edge of roller c while the rimrevolved between the rollers c c' by means of the conical roller S, Fig.1, .which -is brought to bear against the upper outer edge of the metal,which is vertically straight, Vas in Fig.

5, and as the metal yields a continuous and increasing pressure of theroller S is brought to bear upon it until it is nally at right angle tothe tread part of the wheel-rim, as shownat the rightof Fig. l. f 5

Any suitable means may be employed to-opcrate the roller S. It is shownattached to a 'curved swinging bar, T, having end bearings..

rollers c c', and the metal band is placed be- 9o` tween theserollers ofeach sct. The rollers c C'. are then brought to bear against-the bandand the machine setin motion. Thefrictional v engagement of theserollers with said band causes it to revolve. has been' formed by theroller S, as before stated, then the rollers a a are brought to bearagainst the band or rim until it is bent to form After the internalHarige tagt the external iange,h as appears in Figs. 1 and 3. Theseflanges can be formed without having the two sets of rollers in,position to receive therim between the rollers a e' and c c' at the sametime; but this would necessitate taking the rim from one set and-placingin another, whereas, as here shown, the rim does not have to be removeduntil it is perfected. Besides, by allowing the operation to continueafter the iianges are formed unevenness and irregularities in thedesired true circular form of the wheel-rim are overcome. The shafts y yand u u have bearings at the lower end in pivoted rocking blocks m,Fig. 1. By this means the shafts can be separated to separate therollers when putting in the rim B and when desiring to take it ont. BothSets of shafts can be tilted slightly to properly locate the rollers.Aswell can the shafts of either set he tilted independently of eachother.

Fig. 4 clearly shows the means for tilting the shafts and holding themat desired positions. To the bearing of the shaft y at the upper end,and to a cross-head swiveled on screw 2, are pivoted the draw-bals c,one on each side.

lThis scnew has threaded bearings in the machine-frame. By turning thehandle or rather wheel V the angle of shaf't 1/ can be changed, andhence the position ofthe roller a' as well. The bearing o1 the shan; -1/has screw-connections with the screw 1, said screw passing through ascrew-threaded hole in the screw 2, the latter-named screw being, ofcourse, hollow. By turning the wheel r of screw 1 the shaft `1/ may betilted.

In the operation of tbl-ming the external fiangeofthe wheel-rim ll the,wheel rand screw 1 are turned to gradually force or press the roller uagainst the rim, which yields a little at a time until it is finallycrimped, as shown in Fig. A great advantage of these screws asa meansothandling the shaft and rollers is that it can be quickly donc and withgreat accuracy, and the rollers are rigidly held at any given point ofadjustment.

Like rollers and screws are duplicated on the other side ot` the machineto handle the i shafts u u' and their rollers.

these rollers maybe dispensed with, if preferred. to the brackets- 3 3,and lluse brackets are connected at the upper ends by 'a shall. s, whichhas screw-threaded ends passert lt rough screw-threaded holes in `saidbrackets. By loosening the nuts whieh hold the brackets The-axles ot`these rollers are attached and turning the shaft 4 the rollers F F areadjusted laterally. In Fig. 1 is shown how the shafts are gear-connectedwith the power-shaft 5, (shownpbroken in Fig. 2;) but any other suitablepropelling mechanism may bc employed.

It may be mentioned that it is not always necessary that the shatts y ushould have bearings which enable them to be tilted, and with accurateconstruction and proportionA of parts perhaps never, but desirable,however, for contingent needs.

Having thus described the invention, what is claimed is- 1. In a machinefor forming wheel-rims,the combination of two revoluble rollers adaptedto receive and revolve the whcelrim between them, a conical roller, andmeans t'or sustaining a pressure ot' said roller against tfie edge ofthewheel-riin in *forming the interna flange, substantially as setforth. t

2. In a machine for forming wheel-rims,the combination of two revolublerollers adapted to receive and revolve the wheel rim between them, tworevoluble rollers, one tapered and the other tiared at the base, andadapted to receive the wheelrim between them, and means for sustaining apressure of' said rollers against the revolving wheel-rim in forming theexternal tlange, .substantially as set t'orth.

3. In a machine for forming whccl-rims,the combination of the revolublerollers adapted to receive and revolve the wheel-rim between them, theconical roller, and means tor sustaining a pressure of said rolleragainst the edge ot' the wheel-rim in forming the internal flange, the.revoluhle rollers, one. tapered and the other fiarcd at the base, andone of them being longer than the other and flanged at the top, saidrollers adapted to receive the wheelrim between them, and means t'orsustaining a pressure of' tl1ese.rollers against the wheel-ri m informing the external flange, substantiallyv as set forth.

L In a machine foi ie. .ning wheelrimsahe combination ot' the sets ofrollers const rncted and arranged, as set f'orfh, to l'orln the intel'-nal llange and external flange of the wheelrim, and means for operatingthem, and the single idle-rollers adapted to contact the inner surfaceot' the revolving wheel-rim, substantially as set t'orth. y
